Abstract

L'invention porte sur un circuit respiratoire comportant un premier et un deuxième conduit dont l'un au moins est non usuel. L'invention porte également sur un circuit respiratoire monolithique comportant un premier et un deuxième conduit dont les extrémités proximales sont reliées respectivement à un raccord d'entrée et à un raccord de sortie, le mouvement de l'extrémité distale du premier conduit entraînant un mouvement correspondant de l'extrémité distale du deuxième conduit. Dans une exécution, l'un desdits conduits est en spirale. Dans une autre exécution, un conduit en spirale est placé dans un conduit extérieur flexible compressible et extensible axialement de manière à constituer un circuit respiratoire monolithique à plusieurs lumières. Le conduit flexible extérieur peut être en accordéon pour permettre son extension ou sa contraction axiale. Le circuit respiratoire à plusieurs lumières peut fournir un volume variable de rerespiration. Dans une troisième exécution, au moins un tube du conduit respiratoire à plusieurs lumières peut se comprimer ou dilater axialement jusqu'à un rayon maximal pour transporter les gaz de la respiration entrant dans le patient ou en sortant. L'invention porte également sur des procédés et systèmes optimisant l'utilisation des gaz frais en ventilation artificielle ou assistée y compris lors d'anesthésies.
